DOUBLE WATER-SCOOP.

1 b all whom it may concern Be it known that I, TVILLIAM B. SMITH, acitizen of the United States, and a resident of Gardena, in the countyof Los Angeles and State of California, have invented a new and ImprovedDouble ater-Scoop, of which the following is a full, clear, and eXactdescription.

This invention relates to improvements in double water scoops, and hasfor an object to provide an improved structure designed to be used uponthe tender of a locomotive, or any other desired place, whereby watermay be easily taken up and also discharged while the tender andlocomotive are moving in either direction, or standing still.

A further object of the invention is to provide a double scoop structurewhich may be adjusted for causing cold fresh water to be taken up and atthe same time discharge the warm water, or upper strata of water in thetank on the tender.

Another object of the invention is to provide pumps in connection withthe double scoops, so that water can be drawn up and forced into thetank while the locomotive is running at any speed or standing still.

A still further object of the invention is to provide a water scoopstructure in which the water taken up may be distributed or directed tothe bottom of the tender, or a receptacle for receiving the waterwithout appreciably agitating the water in the tank.

In carrying out the objects of the invention, it will be, of courseevident, that the device could be attached to a tender, or to any othersupporting means which is adapted to be moved over a track, so that theword tender when used in this specification is intended to cover anyproper sup port for a device. Arranged in the tender, or forming part ofthe tender, is a tank in which a pair of discharge members are p0-sitioned, having one end extending through the bottom of the tank to aposition near the track where they are connected with pivotally mountedscoops operated by suitable means, as for instance a compressed steamoperated rod and lever mechanism. The scoops are connected together sothat when one is lowered, the other is correspondinglylowered. Arrangedin the tank are valve members connected with the pipes to which thescoops are secured, so that when one scoop is forcing water into thetank, the

valve member associated with the opposite pipe and scoop may be openedfor permitting the discharge of the impure or heated water near the topof the tank. Suitable manually operated rods and levers are provided formanipulating these valves as occasion may demand. A practical embodimentof the invention 1s represented in the accompanying drawings forming apart of this specification, in which similar characters of referenceindicate corresponding parts in both the views. Figure 1 is a sideelevation of a tender showing an embodiment of the invention ap pliedthereto, part of the tender and part of the embodiment of the inventionbeing broken away for better illustrating the construction andarrangement; and Fig. 2 is a detail fragmentary side view of the scoopsand associated parts in their elevated or raised position.

Referring to the accompanying drawings by numerals, 1 indicates a trackof any desired kind having a trough 2 of any desired or preferredconstruction, which is maintained full of water so that when the trainhaving a scoop passes over track 1, the same may take up water asdesired. The tender 8 resting on the track 1 is provided with a tank 4in which are mounted pipes 5 and 6. The pipes 5 and 6 have connectedwith the inner ends thereof discharge nozzles 7 and 8, which nozzlestaper from the top to the bottom so that when the water is dischargedfrom either of the nozzles the same will not agitate to an appreciableextent the water in the tank 4. The pipes 5 and 6 are provided withvalve structures 9 and 10 which preferably are merely hinged covers orseats. These valve structures have connected therewith operating rods 11and 12, which in turn are connected with bell crank levers 13 and 14.The levers 18 and 14 have pivotally connected therewith rods 15 and 16which extend to the front of the tender 3 and are preferably providedwith handles so that the same may be easily moved back and forth foropening and closing the valves 9 and 10 whenever desired.

As clearly shown in Fig. 1, the pipes 5 and 6 extend downwardly throughthe bottom of the tender to a point adjacent the track, and havepivotally connected there with scoops 17 and 18 rounded or inclined inopposite directions so that water may be taken up and dischargedsinnlltaneously regardless ot the direct ion of movement of the tender.'lhcse scoop structures may be of any preferred or ordinary constructionso that the same will need no further detail description, the same ofcourse closing pipes 5 and 6 when raised to the elevated position asshown in Fig. 2. The scoops 17 and 18 have connected therewith links 19and 20, which in turn are connected with bell crank levers 21 and Thebell crank levers 21 and are pivotally mounted on suitable bracketsextending from the tender 3 so that when the ti-ounecting link 23connected therewith is operated. the levers will he moved for causinglinks 19 and. 20 to raise or lower the scoops. The pivotal pins whichconnect link with bell crank lever 22, also connect link 2% with bellcrank lever 22 so as to connect a piston rod with link '23 in order thatthe scoops may be properly operated and operated simultaneously. Thepiston. rod is connected with the piston :26 mounted. in a suitablecylinder 27 so that when stean'i pressure is allowed to pass throughpipe 28 by the proper operation of valve 29, the piston 96 will be movedagainst the action ol spring 30 for elevating the scoops. The valve 29may be of any desired construction for turning on steam ire to pip-e 28from the usual steam ire line. This valve structure, how ever, must beprovided with a port for per mitting the pipe 28 to exhaust when thevalve 29 is closed oil so as to permit spring 30 to operate for loweringthe scoops 1'7 and .8. D will he evident that the spring 30 could beused for raising the scoops and the steam pressure used for lowering thesame against the action of the spring.

In operation, when a tender is going in either direction, and it isdesired to take on some water, the valve 29 is operated for lowering thescoops when the same come to a point above trough 2. The movement of thescoops througl'i the water will cause the same to be driven througheither of the pipes 5 and G and to be finally discharged into tank 41:.It, for any reason it is desired to discharge the upper strata of waterin tank t, one of the valves 9 or 10 is opened. This is very desirablewhee the water from the tender is used in the condenser or for coolingpurposes in any desired structure. As for instance, when used in a steamcondenser the water becomes heated and when in such condition willretard the condensing of the steam. To overcome this, the valves 9 and10 are provided and the double scoop structure, so that cool water maybe maintained in the tank t and the warm water discharged. It will beevident that the scoops may be worked together, or imlependent-ly, andbe operated manually or by power.

In some instances it has been found that the scoops which scoop up thewater from the track tank will splash the water and thus *aste the same,while not forcing the proper amount into the tank. T0 obviate thesedisadvantages, and to insure the proper taking in of the water, a pumpin the form of a screw or propelling device 31 is provided in each ofthe pipes 5 and (3, de signed to operate in opposite directions so thatwhen water is being forced into tank 4; thrmigh pipe (3. water will beforced from the upper part of tank 1 through pipe 5 into the trough 2,'provided'the valve member 9 is open. The pump or screw 31. is providedwith shatts 232 and 33 which have gear wheels socured to their upperends and (amt-imially meshing so that the motor 3t connected. to one ofthe shafts or 3?) will operate both shafts and consequently willsimultaneously operate both ol the screws 31, the same of courseoperating in opposite directions as just described. In providing thesescrews and the double arrangement of scoop, the same may be used fortaking up water at any time and for any purpose, but the ar rangementoi" the pipes 5 and 6, discharge nozzles 7 and 8, and the valves 9 and10 is used to maintain as far as possible a cool fluid in tank a, or atleast in the bottom of tank l, so that the same will be utilized forcooling purposes in the condenser for the engine, or for any otherdesired purpose. ll hen it is desired to remove water from tank l forthe engine, the same is preferably taken from the top strata of water,as the same is warmer than the lower strata, while water is taken fromthe lower strata when the same is designed to be used in a condenser forcondensing the steam from the cylinders of the engine, or the turbine ofthe engine, in *ase a turbine is used. It will be evident that the coldwater may be used for any pru'pose, the above being given merely asillustrations. It will he noted by the use ot the pumps that water maybe taken up from a, track tank while the locomotive is running at eithera slow speed or at very high speed with comparatively little waste ofwater, as there will be a sucking action on the water in addition to theusual force exerted through. impact. It will also be noted that it willbe possible to pump water not only from a track tank. while the train ismoving slowly, but when the train is standing still. It will be evidentthat a centrifugal or any other suitable pump may be used.
